This invention relates to anew and improved sanitary waste receptacle, and more particularly to the type having a removable paper bag for the convenient and sanitary disposition of the contents.

Waste receptacles of various constructions have been proposed with a view to use of a disposable paper bag. However, careful analysis shows that they have all been objectionable in one important respect or another. That is to say, if the receptacle was constructed with a view sitate practically the complete dismantling of the. whole receptacle to permit removal of the filled bag through lthebottom, thus. necessitating the. handling of every part of thereceptacl'e, which work could hardly be done without thoroughly soiling the hands and possibly spilling the contents of the disposable bag. Some of the con-.

structions proposed, in which the body ofthe receptacle is remov'ably supportedona base are clearly impractical becauseof thedanger of having" the receptacle come apart. anytime that the,

cover is taken off or raised. It is, therefore, the principal object of my invention to provide a truly sanitary receptacle, which while it permits quick and easy as well as sanitary removal of the disposable bag avoids the objections noted in regard to prior constructions.

metal body of the receptacle, which is preferably, though not necessarily, ofcylindrical form. Square or rectangular receptacles may be provi'ded, more closely approximating the shape of the disposable paper bag 6, the aim being to utilize bags of a form commercially available at low cost without reducing too much the capacity of" the receptacle and making. it necessary to replace bagstoo often; I have found that a standardfform and size of paper bag can be spread at the-mouth to fit neatly inside the cylindricalbody. 5,'wi1thout having too much waste space aroundf'the bottom of the bag, and there is no diflicult y in the use of such a bag when the mouth of; thebag is kept spread wide open by a sheet metal collar T- provided in accordance with my invention. The paper bags may be waxed orotherwise waterproofed' and will cost so little that they may be thrown away or burned with the-contents. bottom 8 which may be on? wood and fastened inplace by screws" or nails, as indicated at 9, passed through the walls of .the body The invention is illustratedv in the accompany- 5 servesto support'the disposable bag 6 with the month end l 0- extending up to; or close to, the:

upper rim H" ofthe body 5. The rim portion H is preferably curled" outwardly tolend strength andrigidity-tothe mouth portion of the body. The bottom portion l2 of the body 5 is preferablycurled' outwardly in the same way for the same purposqand the receptacle will, of course, rest on the floor l3" on this bottom rim. The collar 1 is made from sheet metal and is of circular form, and slightly larger in diameter'at the outwardly flanged upper end I4 than at the lower end; so that the upper end portion will fit closely inside the mouth end- Hlof the disposable bag when the collar is; in place with the flange l4 resting on and-extending outwardly slightly beyondthe outer-periphery of the top rim ll of the body'ii; as-illustrated in Fig. 1. In that way, thecollarcan-'be inserted easily without danger of damaging or d-i'splacing themouth portion l0 oi the bag, althoughitserves thereafter to hold the mouth'portion of'the-ba g in place throughout the 'filling of the receptacle. When the receptacle is'filled and 'the bag 6 -is to be removed; the collar 1 can be raised, as shown in Fig. 2, by engagement of the finger tips with the outer periphery of the flange 14. The extent to which this flange projects beyond the top rim ll makes it a simple matter for the operator to grasp it firmly enough to remove the collar without even touching the receptacle. The outer periphery of the flange is, moreover, far enough removed from the inside of the collar that there is little or no likelihood of V be clear from the foregoing description.-

the fingers being contaminated in the handling of the collar 1, and, of course, once the collar is removed, it may be placed on the floor with the flanged end on top While the filled bag 6 is being removed and a new bag is being inserted, after which the operator can pick up the collar 7 by handling it in the same way as before and insert it in the mouth of the new bag inside the receptacle. The collar 1 throughout the filling of the disposable bag affords ample protection for a sunicient length of the bag, in relation to its depth and diameter, at the month end ill of the bag so that the operator will have no difi'iculty in removing the bag and closing the same thereafter, it necessary, in so far as any danger of soiling the hands is concerned. When the lid l for the receptacle is closed, it has the outer rim ceptacle, and has an operating link l9 pivotally connected thereto, as at 20, in radially spaced relation to the pivot H. In that way thetreadle 2| that is pivoted intermediate its ends, as at 22, on a cross-bar 23 in the bottom portion of the body 5"of the receptacle is arranged when depressed to raise the lid, as illustrated in Fig. 2, the outer end portion of the treadle 2| projecting through a'slot in the side wall of the body 5 below the bottom-piece 8 for pivotal connection with the lower end of the link l9, as indicated at 24.

The operation of the receptacle is believed to The construction is relatively simple and inexpensive and avoids the objections noted in regard to prior constructions. A receptacle of this type may, of course, be used wherever the novel features pointed out are of advantage. It may be used in the home, for example, as a receptacle for garbage, or it may be used in the toilets of schools and public buildings as a waste receptacle generally.

It is believed the foregoing description conveys 'a good understanding of the objects and advantages of my invention. The appended claims have been drawn to cover all legitimate modifications and adaptations.

I claim:

1. In a sanitary waste receptacle comprising a substantially cylindrical open-mouthed container having an outwardly projecting rim defining the mouth portion and containing a removable and disposable paper liner bag having the open end of the bag disposed in the open upper end of said container, means for holding open said liner bag and clamping the upper end thereof and protecting the clamped portion from contamination so that the bag may, when filled, be readily removed from said container without likelihood of a person soiling his hands on said bag in so doing, said means comprising an elongated substantially circular sheet metal collar presenting a substantially smooth inner surface throughout its circumference, said collar being of approximately the same outside diameter at the top thereof as the inside diameter of the container, said collar being slightly tapered substantially the full length thereof so that it is only slightly smaller in diameter at its lower end, whereby to facilitate entry of the lower end of said collar into the mouth of the bag and provide for wedging engagement of the upper end portion of the collar in the mouth of the bag,

" clamping the mouth portion in surface-to-surface of the container, said collar being of a length sufficierrt in relation to the depth and diameter of the bag to prevent contamination of enough of the'mouth end portion of the bag to permit removal of the bag by a person without soiling his hands, and an annular outwardly projecting flange on the upper end of said collar adapted to rest on the rim of the container for support of the collar therein, said flange projecting outwardly sufficiently in relation to the rim of the container to be easily grasped by the edge portion thereof for easy removal and replacement of the collar by a person without having his fingers placed in contact with the container.

2. In a sanitary waste receptacle comprising a substantially cylindrical open-mouthed container having an outwardly projecting rim defining the ,nfouth portion and containing a removable and disposable paper liner bag having the open end of the bag disposed in the open upper end of said container, meansfor holding open said liner bag and clamping the upper end thereof and protecting the clamped portion from contamination so that the bag may, when filled, be readily removed from said container without likelihood of a person soiling his hands on said bag in so doing, said means comprising a substantially circular collar of suitable material impervious to moisture presenting a substantially smooth inner surface throughout its circumference, said collar being of a length to reach nearly half the depth of the bag and being of approximately the same outside diameter at its upper end as the inside diameter of said container, and being slightly tapered substantially its full length and being only slightly smaller in diameter at its lower end than at its upper end, whereby to facilitate entering the collar in the bag and providing for wedging engagement in the mouth of the bag while protecting substantially the full length of the upper portion of the bag that is covered by said collar from soiling, said collar having an annularly outwardly projecting flange on the upper end thereof which rests on the projecting rim of the container for support of the collar, said flange projecting radially sufficiently in relation to the rim so that it may be easily grasped by the edge portion thereof for easy'removaland replacement of the collar.
